PAUL GODLEVSKI, 0F SUNBURY, PENNSYLVANIA.

INSECT-EXTERMINATOR.

Application filed February 12. 1913.

To all LU/LOW, it may concern:

Be it known that 1, PAUL G'ODLEVSKI, a citizen of the United States,residing at Sunbury, in the county of Northumberland and State ofPennsylvania, have invented certain new and useful Improvements inInsect-Exterminators, of which the following is a specification.

My invention relates to new and useful improvements in insectexterminators and more particularly to that type of exterminatoremployed in treating growing grain to protect it from insects by dustingthe ground after the grain is planted with ground lime or other suitableinsecticide and the. object of my invention is to provide a machinewhich will evenly distribute the lime, thus not only avoiding wastethrough uneven distribution, but also avoiding danger of killing thegrowing plants "by burning out the ground in spots, due to an excess oflime.

A further object of my invention is to provide a machine of the abovedescribed type which may be employed with equally good results as aguano, spreader.

A further object of my invention is to provide means for adjustablyvarying the amount of lime or other substance being spread. v

With these and other objects in view, my invention will be more fullydescribed, illustrated in the accompanying drawings, and thenspecifically pointed out in the claims which are attached to and form apart of this application.

Corresponding and like parts are referred to inthe following descriptionand indicated in all the views of the drawings by the same referencecharacters.

The preferred embodiment of my invention consists primarily of a wheeledsupporting frame carrying a hopper provided with a feed mechanism whichmaybe readily governed to control the feed of lime or other materialfrom the hopper and a vibrating screen or shaker positioned to receivethe lime or other material as it is fed from the hopper and to spreadthe same evenly over the ground, the feed mechanism and vibrator beingdriven by a common shaft which is in turn driven by the axle.

The body proper of the machine includes a substantially rectangularshaped frame 10. preferably'formed of angle iron and suitably bolted;riveted or otherwise fastened as shown at 11 and provided adjacent itsforward end with a brace 12 extending from one side of the frame to theother. The side members 13 and114c of this frame each carry a downwardlydepending bracket 15 having a bearing 16 providing journals for the axle17. Supporting wheels 18 of anv preferred type are loosely mounted uponthe ends of the axle in such a manner as to normally turn the axleduring the forward movement of the machine in a way which will behereinafter explained. A draft tongue 19 is bolted or otherwise securedto the central portion of the front member 20 of the frame and the framemembers 12, while downwardly depending hangers 21 carried by the rearthe bottom 26 and front and rear sides 27 and 28 are preferably formedof sheet metal, the lower edges of the front and rear walls being turnedinwardly to support the bottom which is riveted to the inturned portionsof said walls, while the upper edges are inturned to support a top 29formed in two parts hingedly connected as at 30, one of these parts 31being rigidly secured to the hopper, while the other part 32 isunconnected to the hopper and forms a swinging closure through which thelime or other material may be supplied to the hopper, this top portion32 being preferably provided with ahandle 33 by means of which it may beraised. The bottom 26 of this hopper is provided with a feed slot 34which extends from one side of the hopper to the other and through whichthe lime or other material passes. The amount of material passingthrough this feed slot is governed by a sliding gate or closure 35 whichrests flatly upon the upper face of the bottom 26, being somewhatgreater in width than the width of the feed slot and having upwardly andoutwardly directed ears 36 at its ends which are movable in horizontallydisposed slots 87 formed in the end walls of the hopper. Slidingclosures 38 are mounted on these ears between the body portion of theygate and the end walls of the hopper and are pro vided with openingsjust sufficient in size to permit the passage of the ears. Theseclosures 38 bear against the inner faces of the side walls of the hopperand form a closure for the slots 37, thus preventing any leaking of limethrough the slots.

A rocker shaft 39 is mounted for rotation. in the side members of theframe adjacent their rear ends and carries at one end a hand lever 40and at its other end a crank arm 41. A link 42 pivotally connects theintermediate portion of the hand lever 40 with the adjacent ear 36 ofthe closure or one of a plurality of notches 45 formed in the lower edgeof an arcuate rack bar 46,

one end of which is pivoted to the side member 25 of the hopperand theother end of which terminates in a handle 47. It will of course beapparent that this rack bar may be swung about its pivot point todisengage the pin 44 and permit the desired movement of the lever 40 toadjust the gate'when' it may be released to engage the pin and lock thegate in adjusted position.

Disposed immediately below the hopper and in fact bearing by its openupper end against the bottom of the same, is a vertical chute 48 whichincloses the feeding and spreading mechanism of the machine and whichalso serves to prevent blowing of the lime or other material beingscattered, the lower end of this chute extending to within a few inchesor a footof the ground and being open to permit the passage of the lime.The feeding mechanism of this machine comprises a cylindrical drum 49which is mounted to rotate with a shaft 50, the ends of which arejournaled in bearings 51 carried by the brackets 15. As best shown vinFigs. 2, 5 and 7 of the drawings,this drum consists of a tubular bodyportion formed of sheet metal and corrugated or ribbed longitudinallythroughout its length, the body member being supported upon and securedto the aXle by castings 52, each of which includes a hub 53 and radiallydirected spokes 54 having laterally formed shoulders 55 at their freeends to which the body portion is bolted or riveted, the hubs of thecastings being secured to the shaft 50 by bolts 56. The shaft 50carrying this feed drum is so disposed'as to position the drum directlybeneath the feed slot 34 of the hopper and the corrugations or flutesformed between the ribs are so proportioned that when the drum isrevolved at a suitable rate of speed, the lime or other material willpass into the corrugations and be carried by the drumand finallydeposited in the chute as clearly illus trated in Fig. 2 of thedrawings. This drum should preferably be positioned so close to thebottom of the hopper that even when the gate is fully opened, no lime orother ma terial will be able to pass from the hopper except that carriedin the flutes and by the ribs of the drum, the drum therefore furnishingan absolute limit for the amount of material fed from the hopper, whilethe gate provides for adjusting the feed of material to the drum.

The chute 48 is provided adjacent its lower end and at each side with apair of vertically spaced apart tie rods 57 forming supporting guidesfor the frame of a screen 58, the bottom of which is formed offoraminous material 59 of any suitable mesh depending upon the materialto be spread. This screen is so proportioned as to extend entirelyacross the chute from one side to the other, but fits loosely betweenthe front and rear walls of the hopper as shown in Fig. 2, this loosefitting of the screen per mitting the same to be vibrated to uniformlyscatter the lime, salt or other material fed to it by the drum.

As previously pointed out, the axle 17 is rotatably mounted in itsbearings and is normally driven by the supporting wheels 1.8 duringmovement of the machine, the revolving axle in turn driving the feedingdrum and vibrating the screen. To accomplish this, the supporting wheelsare mounted upon the axle in a peculiar manner, the wheels being heldagainst inward movement along the axle by means of collars 60 and 61which are secured to the axle by bolts 62. The outer ends of the wheelhubs are each formed with radially disposed clutch teeth 63, the forwardfaces of which are inclined as shown.

Mounted upon the free ends of the axle are sleeves 64 upon which areslidably mounted clutch members 65 having clutch teeth 66 adapted forlocking engagement with the teeth 63 of the wheel hub. T he slidingmovement of these clutch members 65 is limited by pins 67 extendingthrough longitudinally formed slots 68 of the clutch members, throughthe sleeves 6i and into the axle. These pins also look the clutchmembers against rotation independent of the axle. The slots 68 aresufficient in length to permit the disengagement of the teeth 63 and 66but the clutch members are normally held in innermost position andtherefore in locking engagement with the wheels by means of helicalsprings 69 positioned over the ends of the axle and held in place bycollars 70 and pins 71, the normal tension of these springs, when sosecured, being suflicient to hold the clutch members in active position.

The inner face of the collar 60 is provided with a plurality of radiallydisposed clutch teeth 72 adapted for locking engagement with similarclutch teeth 73 formed upon the outer end of the hub 7a of a spur gearwhich is freely mounted upon the axle. Abracket 7 6 extends from theadjacent side member of the frame 10 and pivotally mounted intermediateits length upon this bracket, is a hand lever 77, one end of which isoperatively connected. to the hub 74k of the gear 75 as shown at 78,this hand lever serving as a means for throwing the above describedclutch in and out of position.

A spur gear 79 is keyed upon one end of the shaft 50 in such a positionas to mesh with the gear '75 when the latter is moved to bring itsclutch member into engagement 8 with the clutch collar 60. A sprocketwheel 80 is keyed upon the opposite end of the shaft'50 and a chain 81is trained over this sprocket wheel and over a sprocket wheel 82 whichis keyed upon one end of a shaft 83 disposed parallel to the shaft 50and journaled in bearings 84: carried by the forward lower portion ofthe chute 48. One or more ratchet gears 85' are keyed upon this shaft 83and the screen 58 is provided with forwardly directed pins 86 whichengage against the teeth of the ratchet gears, being held in constantengagement therewith by the tension of helical springs 87 surroundingrods 88 carried by the screen frame and extending through the front wallof the chute, these springs bearing between the chute and heads 89 ofthe rods to normally hold the screen in advance position with its pins86 engaging the base of the ratchet teeth as shown in F ig. 2 of thedrawings. It will therefore be apparent that upon the rotation of theshaft 83, these pins will be intermittently forced rearwardly to movethe screen rearwardly and then released.

when the springs 87 will immediately draw the screen forwardly, thisresulting in a. rapid vibration of the screen.

The side walls of the chute a8 are preferably provided immediately abovethe vibrating screen with doors 90 of any suitable con struction whichare normally closed but which. may be opened to permit cleaning of thescreen, if necessary. If desired, the lower end of the chute may beprovided with a plurality of hooks 91 upon which may be stretched andsupported a strip of can vas or other fabric to form a"continuation ofthe chute for use during windy weather to prevent undue blowing of thelime or other material being spread by the machine, although in mostinstances this will not be found necessary.

In operation, the hopper 24 is filled with the ground lime, guano, saltor other material with which the ground is to be treated and the cover32 closed. The lever 40 is then actuated. to open the gate to such anextent as to feed the desired quantity of the lime or other material tothe feeding drum and the lever 77 manipulated to throw the clutch intoactive position and the gear 75 into mesh with the gear 79. The machineis then drawn about the field in the usual manner, the operator standingupon the platform at the rear of the machine to drive the horses and atthe same time adjust the spreading of the lime or other material by suchmani 'iulation of the gate as may be necessary. The revolving of thesupporting wheels act through their teeth and the teeth of the clutchmembers or sleeves 65 to re shaft 50 also drives the shaft 83 and theratchet gears carried by this shaft engaging against the extending pinsof the vibrating screen, together with the springs, normally supportingthe screen in advance position,

cause a rapid vibration of the screen which effectually spreads the limeor other material delivered into the chute over the ground beneath themachine. As the feeding and spreading of the lime or other material isdirectly proportional to the rate of speed at which the machine travels,it will be apparent that a uniform spreading of the lime over the groundwill be accomplished, irrespective of the rate at which the machine isdriven. The springs 69 are of sufiicient strength to lock the clutchsleeves into engagement with the teeth of the wheel hubs under normalconditions, and consequently cause rotation of the axle to operate themachine in the abovevdescribed manner but at the same time if themachine becomes clogged for any reason, the added load thus put upon theaxle will overcome the tension of the springs 69 and the inclined facesof the co-acting teeth will cause the clutch sleeves 65 to moveoutwardly toward the ends of the axle and permit the Wheels to rotateidly, thus avoiding all danger of breaking delicate parts of themachine.

From the foregoing description, it will be apparent that I have providedan extremely simple and effective form of insect exterminator and one bymeans of which the ground lime or other material with which the earth isbeing treated may be automatically and evenly spread, irrespective ofthe rate of speed at which the machine is operated. It will further beapparent that I have provided an extremely simple and effective meansfor feeding predetermined quantities of the lime to the spreadermechanism proper to suit various conditions and that this mechanism isso arranged that any lumps of lime will be thoroughly broken up beforethey pass to the screen.

Although I have fully described the details of construction of aparticular form of machine, it will of course be understood that thesedetails may be changed at any time, within the scope of the appendedclaims, without in the slightest degree departing from the spirit of'myinvention.

In order to prevent the lime or other material used from clogging thefeed slot in,

the bottom of the. hopper, I have provided the front and rear walls ofthe hopper adj acent their ends with bearings 92 in which are journaledrearwardly extending, spaced apart parallel shafts 98. the rear end ofone of which projects through the rear wall of the hopper and carries acrank arm 94:. I These shafts 93 are each provided intermediate theirlength with a downwardly depending arm-95 and pivoted between the freeends of these arms, is a bar 96 carrying a plurality of teeth 97, thearms 95 and bar 96 being so proportioned and arranged as to extendlongitudinally of the feed slot 3% and immediately above the same.

An eccentric cam 98 is mounted upon the axle 17 and a lever 99 ispivoted by one end to the free end of the crank arm 9-i and providedwith a laterally directed fork 100 at its opposite end for engagementwith the cam 98, the lever being held against disengagement from the camby an eye bolt 101 carried'by the hopper and through which the lever ismovable. 1

From the foregoing description of the device, it will be apparent that arotation of the axle will cause the lever 99 to reciprocate verticallyand so rock the shaft 93 carrying the crank arm. T he rocking of thisshaft causes the bar 96 to reciprocate transversely of the hopper andbreak up any lumps of lime or other material contained therein previousto its passage through the slot. It will therefore be apparent that thelime or other material will not only be in a finely divided conditionupon its passage from the hopper, butthat the above device will alsoserve to prevent any clogging of the slot.
